Reconstruction and identification of pairs of collimated $τ$-leptons decaying hadronically using $\sqrt{s}=13$ TeV $pp$ collision data with the ATLAS detector
This paper describes an algorithm for reconstructing and identifying a highly collimated hadronically decaying $τ$-lepton pair with low transverse momentum. When two $τ$-leptons are highly collimated, their visible decay products might overlap, degrading the reconstruction performance for each of the $τ$-leptons. This requires a dedicated treatment that attempts to tag it as a single object. The reconstruction algorithm is based on a large radius jet and its associated two leading subjets, a…

Angular momentum dynamics of vortex particles in accelerators
Experiments with spin-polarized beams of leptons and hadrons typically employ plane-wave states with definite momenta and energies. In contrast, vortex states represent cylindrical waves carrying a well-defined orbital angular momentum projection along the propagation direction. This projection can be arbitrarily large, endowing such particles with magnetic moments orders of magnitude greater than those of plane-wave states. Consequently, vortex particles could complement - or even replace - sp…

A Time-Domain Method of Auxiliary Sources for Efficient Analysis of Transient Electromagnetic Scattering by Moderately Conductive Cylinders
This paper presents a time-domain implementation of the Method of Auxiliary Sources (MAS) combined with the Standard Impedance Boundary Condition (SIBC) for electromagnetic scattering problems involving cylindrical scatterers with finite but moderate conductivity. The proposed approach focuses on solving the two-dimensional problem using a first-order SIBC, which is valid when the conductivity is sufficiently higher than the maximum spectral frequency times the dielectric permittivity of the sc…

It's incredible that the Alberta Premier continues to claim a pipeline to the Northwest (Prince Rupert) is possible. Premier Eby was not there because he was in the middle of a pre-planned trip to Asia (Japan, South Korea, Malaysia). And he said today there won't be any reconsideration of another oil pipeline, "decarbonzed" or not. And Japan has no interest in heavy oil anyway.
"But Eby continued to pour cold water on other premiers' talk of building another oil pipeline across B.C. to the coast, saying there is already the taxpayer-owned Trans Mountain Pipeline, which is not being used to full capacity.
He added that the Japanese don't want heavy oil and thermal coal. And he has not altered his stance against lifting the heavy oil tanker ban on B.C.'s North Coast.”
